Types::TypeTiny - type constraints used internally by Type::Tiny
This module is covered by the Type-Tiny stability policy.
Dogfooding.
This isn't a real Type::Library-based type library; that would involve too much circularity. But it exports some type constraints which, while designed for use within Type::Tiny, may be more generally useful.
StringLike
Accepts strings and objects overloading stringification.
HashLike
Accepts hashrefs and objects overloading hashification.
ArrayLike
Accepts arrayrefs and objects overloading arrayfication.
CodeLike
Accepts coderefs and objects overloading codification.
TypeTiny
Accepts blessed Type::Tiny objects.
to_TypeTiny($constraint)
Promotes (or "demotes" if you prefer) a Moose::Meta::TypeConstraint object to a Type::Tiny object.
Can also handle Validation::Class objects. Type constraints built from Validation::Class objects deliberately ignore field filters when they do constraint checking (and go to great lengths to do so); using filters for coercion only. (The behaviour of coerce if we don't do that is just too weird!)
coerce
Can also handle any object providing check and get_message methods. (This includes Mouse::Meta::TypeConstraint objects.) If the object also provides has_coercion and coerce methods, these will be used too.
check
get_message
has_coercion
Can also handle coderefs (but not blessed coderefs or objects overloading &{}). Coderefs are expected to return true iff $_ passes the constraint. If $_ fails the type constraint, they may either return false, or die with a helpful error message.
&{}
$_
These are implemented so that Types::TypeTiny->meta->get_type($foo) works, for rough compatibility with a real Type::Library type library.
Types::TypeTiny->meta->get_type($foo)

type_names
get_type($name)
has_type($name)
